Electrode systems for use with medical monitoring systems

A method for manufacturing an electrode system, comprising:

• providing a flexible substrate;
• providing a connector interface on the flexible substrate, the connector interface being configured to communicatively connect the electrode system with a monitoring system;
• providing one or more stimulating electrodes on the flexible substrate, the one or more stimulating electrodes being configured to deliver an electrical pulse;
• providing one or more recording electrodes on the flexible substrate, the one or more recording electrodes being configured to receive an electrical signal;
• and
• providing a plurality of conductive traces on the flexible substrate, the conductive traces electrically connecting at least one stimulating electrode or at least one recording electrode with the connector interface, wherein each of the one or more stimulating electrodes has an elongate shape with a length dimension that is substantially greater than a width dimension.

A system for assessing muscle electrical activity in a subject, comprising:

• a motor nerve stimulator configured generate an electrical pulse to stimulate a targeted motor nerve of the subject;
• a recording apparatus for recording electrical activity of a muscle innervated by the motor nerve;
• and
• an electrode system comprising:
• a flexible substrate;
• a connector interface carried on the flexible substrate and configured to communicatively connect the electrode system with the system for assessing muscle electrical activity;
• one or more stimulating electrodes carried on the flexible substrate and configured to deliver the generated electrical pulse to a motor nerve of the subject;
• one or more recording electrodes carried on the flexible substrate and configured to receive a muscle electrical activity of a muscle innervated by the motor nerve;
• and
• a plurality of conductive traces carried on the flexible substrate, the conductive traces electrically connecting at least one stimulating electrode or at least one recording electrode with the connector interface, wherein each of the one or more stimulating electrodes has an elongate shape with a length dimension that is substantially greater than a width dimension.
